Answer:
In fluorine, the electrons are tightly held to the nuclei. The electrons have little chance to wander to one side of the molecule, so the London dispersion forces are relatively weak. At a low enough temperature the molecules will all be solids. At a high enough temperature they will all be gases.
Answer:
Explanation:
Since, the atomic mass of the elements is a characteristic property of the elements, you can use the data given, number of moles and mass in grams of the product, to calculate the atomic mass of the product, and then compare with the atomic masses of the elements (information foun in any periodic table).
<u>1) Atomic mass of the product</u>:
- Atomic mass = mass in grams / number of moles
- Atomic mass = 604.4 g / 6.3 mol = 95.94 g/mol ≈ 94.9 g/mol (rounded to three significant figures)
<u>2) Periodic table:</u>
- Molybdenum, Mo, the element with atomic number 42, has atomic mass equal to 95.94 g/mol.
<u>3) Conclusion</u>:
So, you can conclude safely that the element you have produced is Molybdenum.
Answer:
During World War II, rationing was implemented to control the equal distribution of items in short supply. Although the primary goal of rationing was equal distribution, a secondary goal was to free valuable factory resources for war production.

Answer:
chlorophyll
Explanation:
The work of chlorophyll is to absorb light energy from sunlight and transfer it to other molecules used for a process of photosynthesis. This energy is utilized in synthesize carbohydrates using CO2. Further, it also doesn't use in a reaction of photosynthesis hence it acts as the catalyst in this reaction.
